From 8d5d455988d66048ec5b84756581bc3f6f2e55dd Mon Sep 17 00:00:00 2001 From: Andy Polyakov Date: Sun, 25 Jan 2015 14:51:43 +0100 Subject: [PATCH] modes/gcm128.c: fix OPENSSL_SMALL_FOOTPRINT compile failure on affected platforms (PowerPC and AArch64). For reference, minimalistic #ifdef GHASH is sufficient, because it's never defined with OPENSSL_SMALL_FOOTPRINT and ctx->ghash is never referred.
